[SOLVED] Data transfer rate for boot operation mode in EMMC 5.1 standard

[haianh]

Hi everyone,

I looked at the EMMC 5.1 standard from JEDEC and want to know the max data transfer rate in boot operation mode right after power on. I saw f_od max = 400Khz so data transfer rate may equal 400 * 8 * 2 = 6.4 Mb/s = 0.8 MByte/s for max configuration x8, DDR. Is my understanding and calculation is correct? Is the frequency of EMMC and Host controller after power on is f_od until it is changed to f_pp in Data transfer mode? Thanks

After searched internet, I found my answer for my question. My assumption is correct and it is called normal boot which compare to fast boot (max 52Mhz). Some stuff are found from SoC application manual.
